Scientists have discovered a way to embed synthetic biology reactions into fabrics and create wearable and customizable biosensors to detect pathogens and toxins and alert the wearer.
According to the British newspaper, “The Sun”, scientists from the Institute of Biologically Inspired Engineering at Harvard University and the Massachusetts Institute of Technology were able to weave the fabric with sensors that change color when detecting the presence of the “SARS-Covid 2” virus in the patient’s breath, indicating that the face mask gives results within “90” minutes. with similar accuracy levels to standard DNA-based diagnostic tests such as polymerase chain reaction (PCR).
"We have essentially reduced an entire diagnostic lab to a small synthetic biology-based sensor that works with any face mask and combines the high accuracy of PCR tests with the speed and low cost of antigen tests," said Dr Peter Nguyen, research scientist at the institute. The visible color can also tell a person when and where they contracted the virus.
Nguyen explained that the mask made of enzymes that interact with the chemicals in the “SARS-Covid 2” virus is operated by a button and remains natural until the virus enters the mask and interacts with the enzymes, which leads to changing the color of part of it to maintain privacy, stressing that their technology can be integrated into laboratory coats For scientists who work with hazardous materials or pathogens.
